DATA SHEET FREE SPACE ISOLATOR FIF-X-XX-XXX-X-XXXX FEATURES: High reliability Low insertion loss High isolation Optimized for 1310nm, 1490nm and 1550nm wavelengths Wide operating temperature range Clear apertures of 0.45mm to 1.1mm available as standard. Finisar free space isolators are used in various laser assemblies which require isolation to prevent optical feedback. The isolators offer excellent performance with low insertion loss and high isolation. Our proprietary bonding process, and years of volume manufacturing experience, result in a high reliability record. Bare isolator chips survive more than 5,000hrs of damp heat testing without delamination. Available in single stage or semi-double stage options centered at 1310nm, 1490, or 1550nm, the isolators are offered with a range of clear aperture diameters from 0.45mm to 1.1mm as standard. Packaging options include round, open or U shaped housings, see the product selection guide below for further ordering information. Packaging options include round, open and U shaped housings. Single stage isolator, round housing. Semi-double stage isolator, round housing.
